linux-nokia-n900: apply wifi cve fixes (MR 3558)
- Downgrade kernel from EOL 5.18 to LTS 5.15 in order to apply WiFi CVE fixes.
  It is currently not possible to upgrade to newer (5.19+) kernels due to a USB
  regression.
- Modify 0005-iio-accel-st-accel-add-lis302dl.patch so it applies on 5.15.74
- Reinstate 0008-wl1251-specify-max.-IE-length.patch for nl80211 support. Patch
  was dropped because it is in mainline since 5.18

Subject: [PATCH] wl1251: specify max. IE length
This fix is similar to commit 77c91295ea53 ("wil6210: specify max. IE
length"). Without the max IE length set, wpa_supplicant cannot operate
using the nl80211 interface.
This patch is a workaround - the number 512 is taken from the wlcore
driver, but note that per Paul Fertser:
there's no correct number because the driver will ignore the data
passed in extra IEs.
